How to Create an SQS Queue with AWS CDK and Typescript

Introduction

In this lesson, we will learn how to create an SQS Queue with AWS CDK and Typescript. Amazon Simple Queue Service (SQS) is a fully managed message queuing service that enables you to decouple and scale microservices, distributed systems, and serverless applications. It is a reliable, highly-scalable, and cost-effective messaging service that can be used to store and retrieve messages between distributed application components.

AWS Cloud Development Kit (CDK) is an open-source software development framework for defining cloud infrastructure in code. It allows developers to use familiar programming languages such as Typescript to define cloud resources and provision them in an automated and secure manner.

In this lesson, we will use AWS CDK and Typescript to create an SQS Queue. We will also discuss the various components of an SQS Queue and how to configure them.

What is an SQS Queue?

An SQS Queue is a message queue that stores messages sent between distributed application components. It is a reliable, highly-scalable, and cost-effective messaging service that can be used to store and retrieve messages between distributed application components.

An SQS Queue consists of two components: a queue and a message. The queue is a container for messages, and the message is the actual data that is sent between components. Messages can be sent to and received from the queue.

Creating an SQS Queue with AWS CDK and Typescript

Now that we have a basic understanding of what an SQS Queue is, let’s look at how to create one with AWS CDK and Typescript.

Prerequisites

Before we begin, there are a few prerequisites that must be met:

You must have an AWS account.
You must have the AWS CLI installed and configured.
You must have Node.js and npm installed.
You must have the AWS CDK installed.
You must have Typescript installed.

Step 1: Create a new project

The first step is to create a new project. To do this, open a terminal window and run the following command:

mkDIR sqs-queue-cdk
CD sqs-queue-cdk

This will create a new directory called sqs-queue-cdk and change the current working directory to it.

Step 2: Initialize the project

The next step is to initialize the project. To do this, run the following command:

npm init -y

This will create a package.json file in the current directory.

Step 3: Install the AWS CDK

The next step is to install the AWS CDK. To do this, run the following command:

npm install @aws-cdk/core

This will install the AWS CDK in the current directory.

Step 4: Create a Typescript file

The next step is to create a Typescript file. To do this, run the following command:

touch index.ts

This will create a new file called index.ts in the current directory.

Step 5: Write the code

Now that we have all the prerequisites in place, we can write the code to create an SQS Queue. Open the index.ts file in your favorite text editor and add the following code:

import * as cdk from '@aws-cdk/core';
import * as sqs from '@aws-cdk/aws-sqs';

export class SqsQueueCdkStack extends cdk.Stack {
  constructor(scope: cdk.Construct, id: string, props?: cdk.StackProps) {
    super(scope, id, props);

    // Create an SQS Queue
    const queue = new sqs.Queue(this, 'MyQueue', {
      visibilityTimeout: cdk.Duration.seconds(300),
    });
  }
}

const app = new cdk.App();
new SqsQueueCdkStack(app, 'SqsQueueCdkStack');

This code will create an SQS Queue with a visibility timeout of 300 seconds.

Step 6: Deploy the code

The final step is to deploy the code. To do this, run the following command:

cdk deploy

This will deploy the code to your AWS account.

Conclusion

In this lesson, we learned how to create an SQS Queue with AWS CDK and Typescript. We discussed the various components of an SQS Queue and how to configure them. We also looked at how to create a new project, install the AWS CDK, create a Typescript file, and write the code to create an SQS Queue. Finally, we deployed the code to our AWS account.
